Designed as a longer-range, higher-payload replacement for the A-4 Skyhawk, the A-7 Corsair II was first flown on September 27th, 1965. This aircraft entered service during the Vietnam war and later became one of only a few US Navy aircraft to serve with the US Air Force. It possessed cutting edge technologies; it was one of the first aircraft to use a turbofan engine, an internal navigation system and a "head-up" display. Late in its career, A-7s were used for pilot training and were parked outside of hangars in order to draw the attention of Soviet spy satellites away from the fledgling F-117.
